The 4WRPNH6C4B40P-2X/M/24CA6A valve is produced by Bosch Rexroth for the 4WRP Solenoid Valves series and serves in hydraulic automation to meter flow and direct pressure to actuators. It operates in the NG6 size class, and its spool carries the C4 symbol with a P-type inflected flow characteristic to maintain uniform response across the travel range. Rated flow is 40 l/min at a 70 bar differential, and the pressure limits reach 315 bar at the P, A, and B ports while the tank port endures 250 bar. Installation follows the ISO 4401-03-02-0-05 mounting pattern, integrating easily with standard subplates.
The valve draws 40 W from a 24 V DC supply, and the A6 command interface accepts a ±10 V DC control signal. An analog sensor on connector X4 M12-5 delivers a ±10 V feedback voltage, while a digital sensor outputs 1 Vss through X7 M23-12 for alternate monitoring. The actuating time does not exceed 10 ms between 0 % and 100 % stroke, supporting rapid closed-loop control. The housing is sealed to IP65, and reliable operation requires hydraulic fluid filtered to ISO 4406 class 18/16/13. Overall weight is 2.7 kg.
